I solved it thanks to everyone.
I had already found that it was a ram problem and thanks to gbafamily1 I have:
1) I changed the library and added the method CLOSE_ABORT()
(https://github.com/pfabri/Arduino/commi ... 26240bc2f3)
but free heap size goes down
2) I change call the deconstructor directly but I used delete
(https://github.com/esp8266/Arduino/issues/1070)
but free heap size goes down
3) Utilized CLOSE_ABORT() and delete together and worked very well.
the code utilized:

Code: Select all......
void loop() {
  //const int httpPort = 80;//define in the global scope
  //const char* host = "www.google.it";//define in the global scope
 

 
  if((WiFi.status() == WL_CONNECTED)) {
        WiFiClient * client = new WiFiClient();
        client->connect(host, httpPort);//open the connection
                //...... code .......

   //close connection and free heap
        client->stop_abort();
        delete client;

    Serial.println("closing connection");
   }else
   {
     Serial.println("---->not connection");
   }
   delay(200);
 }
....
